Royal Pane Down Under, Ash Pane novel number two
by David and Linda Broughton
Ash Pane, trouble shooter in the literal sense, is asked to take on the job of freeing enslaved aborigines in Australia's Land of the Never-never, by the Queen of England. She must take out the man behind it all, and destroy a uranium mine he's forcing the natives to work. It's no easy task, but Ash gives it her best shot, and gives the bad boys a few shots too.
